Default Radio stopped working

My radio stopped working yesterday in the middle of Come Sail Away.

Yeah I know...

Its lit up and everything, but all you hear when you turn the volume **** is a static like whizzing noise. I tried cds but they didnt work either. But I never tried them when it was working so I don't know.

Any idea what might have caused this and what can fix it? Is it a fuse to the antenna or something like that?

If it is the original it most likely crapped out.

Sometimes radios have easy to find problems such as burned capacitor or resistor.
Check all wires coming to radio, if they are OK open radio and look.

Hmmm, that's interesting. My radio also stopped working today. I wasn't listening to anything as cool as Come Sail Away though. I just turned it on and... nothing. That's like the 2073rd part that has stopped working in the last two weeks. At least my tires still hold air. Oh crap, I better go check out the tires.

Not sure on a 91, but my 86 requires that both the CLK/CTSY and Radio fuses, are intact.

I get a display on the tuner, but that's all. I think my CDM/tuner module took a dump, too.

Could be a relay.

My radio actually started working again this morning. I never turned it off and apparently had turned the volume WAY up to see if maybe that was the problem. It came on all of a sudden this morning and scared the holy hell outta me. I was braking and had just turned on the left turn signal... I'm not sure if that even matters, but there it is.

Probably just wanted you to play better music.

When this happened to me, I replaced the radio relay under the passenger side dash and all promptly returned to normal.

What symptoms were you getting? In my case, I get no sound at all from any speakers and the antenna motor isn't coming on.

However, I get a station display on the head unit briefly, then it reverts to the clock mode.

I believe the CDM/tuner module is the brain behind the whole setup, correct?

Mine has been going in and out since last year. Dr. Don said it was probably power supply in the remote tuner under the rightside dash. It is to difficult to get out of the dash so I installed an Alpine double din from Crutchfield. I used their adapter kit so I used the fatctory wiring.

I don't care if it isnt original.
